Fertility Builder One-Two Year Mixture 70% ORGANIC


A grass and clover mix is the most effective green manure of all for improving soil fertility and structure. To realise its full potential it should be grown for at least one full year before incorporation. Red clover fixes up to 300 kg N/ha which is made available in the form of nitrate and is released rapidly after incorporation. To delay the release of nitrogen, clover should be mixed with grass. The grass is higher in carbon and acts like a sponge, holding the N for longer. This is especially important for autumn-sown crops such as winter wheat where the highest demand for for N can be six or seven months after the green crop has been incorporated. A mixture also offers more weed competition and removes the risk of a single species failure. White clover is included for its ability to improve soil structure. Regular topping, ideally with a flail mower, will be necessary. The first topping will be required in May, followed at monthly intervals until growth slows in August. After incorporation a minimum of three weeks should be allowed before sowing the next crop. These seeds need a fine and firm seed bed. They can be broadcast or shallow drilled (no deeper than 10 mm).

More InfoNaturally occurring, Mycorrhizal Fungi (MF) can provide a higher yielding grass ley with increased robustness, better drought tolerance and better nutrient uptake. Itís particularly beneficial for legumes, but works on all plants (except brassica species) to create a large secondary root system which will support them for their lifetime.

Hybrid Ryegrass

This form of ryegrass is perhaps one of the best grasses available to the intensive farmer. The hybrid ryegrass is a cross between the Italian and perennial forms of ryegrass and shares characteristics of both. The dominant parent determines how the variety performs in the field. Most hybrid varieties are dominant with Italian genes and the best cultivars provide the same or similar high yields as Italian ryegrass. But as they also contain some of the persistent genes of the perennial ryegrass parent they last longer. This longer lasting and high yielding silage grass has one further advantage: the genes of the perennial ryegrass parent produces a plant with more tillers and more leaf which gives increased ground cover, making them better for aftermath grazing.

Large Leaved White Clover

Clover is one of the most popular legumes in the UK, this species can be recognised by its creeping growth habit. Its creeping stolons help to fill in gaps in the sward, putting down roots at each node. White clover varieties can be categorised into small, medium and large leaf sizes. Generally the smaller the leaf size, the more persistent and prostrate the plant will be, the small leaf type will tolerate closer grazing from sheep and tends to sit lower at the base of the sward, the small and medium leaf varieties are used for grazing mixtures. Using mixtures of white clover varieties helps to ensure that at least one can tolerate and contribute to what ever management regime is being imposed at a given time. The larger leaf varieties are more upright and contribute to yield in cutting swards, but they are less persistent. Common large leaf varieties are Alice & Barblanca.

Red Clover

Red clover is one of the most popularly used true clovers in the UK. Once established itís capable of rapid growth and shows reasonably good persistence up to three years, although ongoing breeding work is being carried out to increase plant persistence. The highest yielding strains of red clover are called 'double cut' varieties, normally providing quick regrowth after cutting and several flushes or cuts per season. The 'single cut' strains of red clover, notably the variety altaswede provide one large cut per season, flowering approximately 2-3 weeks later than the 'double cut' strains.
